Parramatta. Drilling for Sydney Metro

Geotechnical investigations are being undertaken at various locations along the proposed route of the Sydney Metro, in the Parramatta area. This work helps determine where it will be best to design and construct the tunnels. A series of bore holes, each with a diameter of 10cm will be drilled and a core sample will be taken from each hole to provide a snapshot of the underground rock conditions in the area.
